This easy vanilla buttercream recipe is my go-to American buttercream for cakes and cupcakes. It’s rich, creamy, full of vanilla flavor, and less sweet than traditional American buttercream thanks to the perfect balance of butter, powdered sugar, vanilla, and salt. It has a smooth, spreadable consistency that’s ideal for filling and frosting layer cakes, topping cupcakes, and piping intricate designs. It also firms up in the refrigerator, making it perfect to use as a frosting base under fondant!


One reader, Iqra, says: “I LOVE this recipe, I have been making buttercream for some time now but I wanted to see if I could make it better, creamier and less sweet. And this recipe was just that! It was so creamy, light, fluffy and the perfect amount of sweetness. Best recipe I have found!” ★★★★★
I’ve tested countless buttercream recipes over the years, and this is the vanilla frosting I come back to again and again. It’s simple enough for beginner bakers but versatile enough for detailed cake decorating, and you can easily adjust the consistency depending on how you plan to use it.

Why You’ll Love This Vanilla Buttercream
- Beginner-Friendly. No cooked sugar, egg whites, or complicated techniques necessary here. This vanilla buttercream comes together in minutes with a stand mixer or hand mixer.
- Less Sweet. This recipe uses less powdered sugar than the average American buttercream and balances the sweetness with salt.
- Perfect for Cake Decorating. The consistency of this buttercream is ideal for filling and frosting layer cakes and decorating cupcakes. You can easily adjust the consistency to make it thinner or thicker depending on what you need it for.
- Strong Vanilla Flavor. You can use vanilla extract or vanilla bean paste here, either way you’ll end up with amazing vanilla flavor.
- Easy to Make Ahead. You can make this vanilla frosting up to two weeks ahead of time stored in the refrigerator, or up to two months ahead if you want to freeze it.

Vanilla Buttercream Ingredients
There are just a handful of ingredients you’ll need for this recipe and it’s simple to whip up for people of all skill levels. I’ll explain what role each ingredient plays in the buttercream and any substitutes you can use:
- Unsalted Butter. This is the base of the buttercream and gives the frosting a rich buttery flavor and velvety smooth texture. If you only have salted butter on hand, you can use that instead and omit the salt at the end of the recipe. And if you want a vegan version of this buttercream, you can follow this recipe which uses vegan butter sticks.
- Powdered Sugar. This adds stability to the frosting while sweetening. I like to use less powdered sugar than the average American buttercream so that the frosting doesn’t end up cloyingly sweet, but if you’d like it even less sweet you can reduce the powdered sugar amount by up to ½ cup (60g). Just keep in mind that the consistency of the buttercream will be thinner.
- Vanilla. You can use either vanilla extract or vanilla bean paste to flavor the buttercream, and making sure you use a quality brand is one of the secrets to success. You can use any kind of vanilla extract or paste, but my favorite brands are Trader Joe’s and Kirkland Signature (from Costco) for vanilla extract, and Nielsen-Massey for vanilla bean paste. If you’re looking for more flavor options, I have all of my frosting recipes here.
- Milk or Heavy Whipping Cream. This thins out the buttercream while binding all the ingredients together. I like to use a liquid with lots of fat for this part because it makes the final frosting more velvety smooth, so whole milk or heavy whipping cream are my go-to’s. If you’d rather use a dairy-free option you can substitute this with any milk alternative, but keep in mind that the flavor of the liquid will affect the overall frosting flavor.
- Salt. A pinch of salt helps balance the sweetness beautifully.

How to Make Vanilla Buttercream
- Whip the Butter.
- Add the Powdered Sugar
- Add the Vanilla, Milk, and Salt.
- Mix Until Smooth.


How to Make the Right Buttercream Consistency
Depending on what you’re using this vanilla buttercream recipe for, you’ll want to consider the final consistency of the buttercream (in other words, how thick or thin it is). I have a detailed blog post on how to achieve the perfect buttercream consistency if you want additional resources. Here are the 3 types of buttercream consistency and what they’re best used for:
| Buttercream Consistency | Best For | How to Make It |
| Medium Consistency (the recipe as-is) | -Filling and stacking cakes -Crumb coating -Frosting a smooth buttercream finish -Piping a buttercream border -Piping swirls onto cupcakes | Follow the exact recipe below |
| Thin Consistency | -Piping a message with frosting -Buttercream painting -Getting a super smooth final coat of frosting (like what I use in this smooth buttercream hack) | Add one extra tablespoon of whole milk or heavy whipping cream at the end of the recipe |
| Stiff Consistency | -Piping buttercream flowers -Piping intricate designs that need to stand upright against gravity (like ruffles on a lambeth cake) -Piping a really sturdy buttercream dam before filling cakes with a soft filling. | Add extra powdered sugar to the recipe, about 2-3 tablespoons at a time, until the desired consistency is reached |
Vanilla Buttercream Tips for Success
This buttercream is simple for anyone to make, but there are a few things to keep in mind when making, storing, and working with it.
- Room Temperature Ingredients. Be sure to use room temperature ingredients. This is important for ingredients to combine and create a smooth consistency. Over the years I’ve found that cutting corners like adding cold milk will create a curdled look in the final frosting because the temperature hinders the ingredients from coming together smoothly. Not the best look! So, take your ingredients like butter and milk out of the refrigerator for about an hour prior to making the frosting.
- Use the Paddle Attachment on Your Stand Mixer. Also known as the flat beater attachment, the paddle attachment is designed to incorporate just the right amount of air into the buttercream. This makes it easier to make smooth buttercream without a ton of air bubbles.
- Whip the Butter for a Long Time. To achieve the smoothest buttercream that’s also nearly white in color, you’ll want to whip the butter for a long time – about 7 minutes. In this amount of time, the butter should go from yellow to almost white and be extra smooth.
- Then Mix Everything Else on Low Speed. After you whip the butter, it’s important to keep the mixer on low speed any time you’re mixing in the additional ingredients. Even though it will take longer to mix the ingredients, keeping the mixer on low speed helps prevent air bubbles from forming in the buttercream.
- Let the Ingredients Fully Combine. After I mix in the final ingredient (salt) I like to run the mixer on low speed for another minute or two to allow everything to combine fully. This gives the powdered sugar time to dissolve as well, so the buttercream will taste smooth and not grainy.

Vanilla Buttercream Troubleshooting + FAQs
- How much buttercream do I need to make for my cake project? It depends! I made this handy chart to help you calculate how many batches of buttercream to make for your specific cake size.
- How do I make my buttercream whiter? This buttercream is pretty white as-is from whipping the butter for so long, but to get it even more white, you’ll either want to add an icing whitener like AmeriColor Bright White or the tiniest amount of purple food coloring (it helps cancel out yellow hues).
- Do I need to sift the powdered sugar? It’s not absolutely required, but to get the smoothest texture for your buttercream, you’ll want to sift the powdered sugar.
- How do I get rid of air bubbles in my frosting? There are a few techniques! I detail them all in this blog post.
- Why is my buttercream grainy? Your powdered sugar isn’t fully dissolved. Keep mixing on low speed until it’s no longer grainy.
- Why does my buttercream look curdled? The most common reason is adding liquid (like the milk in the recipe) that is cold. This seizes up the butter content and creates a curdled look. To fix it, scoop out about ¼ cup of the buttercream and place it into a microwave-safe bowl. Heat it for 5-10 seconds, until it’s melted but not hot. Then, mix it into the rest of the buttercream to re-emulsify the separated fats and liquids.
- Why is my buttercream too thin? This recipe will end up thinner than usual if you start with butter that is too soft or your kitchen environment is too warm. In either of these cases, refrigerate the whole bowl of buttercream for 15-20 minutes to let the butter re-solidify slightly, then re-mix with your stand mixer on low speed until smooth.
- Why is my buttercream hard to spread? Sometimes after storing buttercream, it can thicken naturally and become hard to spread when you’re frosting a cake. In this case, I recommend re-mixing on low speed with your stand mixer and adding 1-2 teaspoons of room temperature milk until the consistency is silky and easy to spread.
- How do I store buttercream? Place the buttercream in an airtight container and store at room temperature for 1-2 days, or in the refrigerator for up to 2 weeks. When you’re ready to use it, bring it back to room temperature and re-mix with your stand mixer on low speed until smooth. You can also freeze buttercream in a Ziploc bag for up to 2 months, then thaw it in the refrigerator overnight before bringing it back to room temperature and re-mixing until smooth.

Hi!! Whitney! Hopping on here to update you that with your tips and buttercream, my sister’s wedding cake was near perfect! Thank you so much for all of your advice on making cakes ahead of time! It really made me feel so much more confident and stress free about the whole thing! I wish I could include a picture of the cake so you could see the final result! This cake was completely iced from bottom to roses in this buttercream recipe (I did 3/4 vanilla extract & 1/4 almond extract to make it a little more “wedding vibes.” Everything piped and smoothed beautifully! This recipe is tried and true! Thanks a bunch❤️
Yay, Analia! I’m so happy to hear that everything went so well!! Thank you for reporting back and feel free to tag me or send me a photo of the cake on instagram: https://www.instagram.com/sugarandsparrowco/ it sounds so lovely and I hope you feel extremely proud of yourself, that was SUCH a big project and you worked so hard! Well done 🙂
Question. I want to make a 2 or 3 layered cake and don’t know how much buttercream to use. Also what does buttercream even taste like? (I have very picky children)
Hi Lucy! I would make 1.5x the recipe to fill and frost a 2 or 3 layer cake, or double the recipe if you’re adding buttercream borders or other piped details. This frosting tastes creamy and sweet (but not overly so) with lots of vanilla flavor. Hope that helps!
